Coarctation of the Aorta (COA)

Coarctation of the aorta is a narrowing of the aorta. The aorta brings blood from the left ventricle of the heart to the body. A narrowing, or coarctation can occur in either a short or long piece of the aorta.  It can occur alone or associated with other heart conditions, typically it occurs with left-sided heart lesions such as ventricular septal defects, mitral or aortic valve abnormalities or hypoplastic left heart syndrome.

Genetic conditions such as Turner’s syndrome can be associated with coarctation of the aorta.
